摘　　要：为验证铰接系统在铰接车前后车架上不同布局方案的差异,利用ADAMS软件建立了铰接车虚拟样机模型,研究了铰接系统前置和后置两种方案对铰接车原地转向过程中轮胎和铰接体的受力、车身侧倾以及运动轨迹的影响。结果表明:采用铰接体前置方案减小了转向过程中前后车体侧倾的现象,内外两侧轮胎轮荷转移量降低了50%以上,铰接体沿整车纵向和侧向的受力也得到一定程度的改善,采用两种方案的铰接车运动轨迹基本重合。In order to testify the effect of articulated body layout scheme on the articulated vehicle frame, the virtual prototype model for articulated vehicle was established by using ADAMS software. The effect of two different articulated body layout form-front-articulated body and rear-articulated body-on the full vehicle pivot steering performances was studied. The results showed that the front-articulated body scheme dropped the phenomenon of body roll in the progress of pivot steering, reduced wheel load transfer between inner side and outside tires by above 50%, and the force on articulated body at the full vehicle directions of longitudinal and lateral was also improved, the motion trail of the two schemes was almost identical.
